Holograms Coming To Your Phone

⊲ Earth.com ⊳ Researchers at the University of St Andrews have developed a compact optical device capable of projecting detailed holograms using light from a single OLED pixel, moving closer to integrating holography into mobile phones. This innovation employs a metasurface, which manipulates light to create images, and a colour filter to enhance image clarity. While challenges remain in brightness and manufacturing, this advancement suggests a promising future for holographic displays in consumer technology. The findings are detailed in the journal Light: Science & Applications.
